I'm trying to plan out my eKeggle ports, and I'm wondering about re-circulation during mash. I assume that I should be directing any flow through my lid and on top of the mash - a dispersion via sparge arm or just letting the tube sit on the mash doesn't matter. But, this is just an assumption. I plan on putting in a whirlpool port and use that for re-circulation while heating the liquid - can I use this during mash instead of through a lid?
